Please kindly note that we have deliberately use the term “modern energy cooking service”. I highlighted “modern” instead of “clean” with the purpose to capture multiple dimensions/attributes of cooking (e.g. clean/health, efficiency, convenience, affordability, availability, and safety which the multi-tier framework is already measuring). I also highlighted “service” to emphasize the need to focus on end users and their preferences. Without focusing on the end users’ needs and their context in mind, any interventions are unlikely to be successful and sustainable. Let’s ensure we have these elements in our ECCH projects design and implementation in order to have more successful stories.
